Escaping escapes (\\)

Does anyone know why you have to escape the backslash in escape sequences?

eg.
AppendToNotepad("test","Fish!\\r\\n")

\n produces very weird syntax errors.. is MUSH pre-processing the sequences before sending them to Lua?

In "send-to-script" it preprocesses them, so you have to quote them twice. In a script file it doesn't.

Mmkay :)
